Question

int main()
{
int i, j, sum = 0;
for(i=0;i<3;i++)
{
for(j=0;j<4;j++)
{
if(j > 2) break;
sum++;
}
}

}

What is value of sum, explain.

Answer 1

Ans: sum= 9

Here the inner loop executes 4 times.

But if 'j' value is greater than 2 then the loop will break.

so, for j=0,1,2 the sum value is incremented.

so, sum is incremented 3 times due to inner loop.

and the outer loop executes 3 times.

so, 3*3=9 times.

so, if increment sum value 9 times from sum=0

the sum value becomes 9.

so, the sum value is 9 after execution.
